What is the newest installment of 'Random Thoughts' on Physics Forums?

In summary, the conversation consists of various discussions about documentaries, the acquisition of National Geographic by Fox, a funny manual translation, cutting sandwiches, a question about the proof of the infinitude of primes, and a realization about the similarity between PF and PDG symbols. The conversation also touches on multitasking and the uniqueness of the number two as a prime number.

Have you ever noticed that in all of the science fiction movies and shows where time slows down or stops for everyone and everything except the main character, it is never dark?

Good point. It should get dimmer and redder as it slows down. Then the main character would need a flashlight - but that would be like X-rays and go right through the slowed folks, so the main character wouldn't see much.

Indeed. That and the fact that the character is able to easily move around without creating sonic booms, not to mention the possibility of actually ionizing the air molecules around them. Yes, I think about that stuff every time.

Suspension of Disbelief gets me through it, though. I do enjoy a good scifi/ghost/fantasy/demon story, even if it isn't altogether realistic.

More shrinkflation:

Last time, I noticed it seemingly at Chick-Fil-A. Now, I'm getting less entree at Panda Express, while the noodle portion seems more (saw that with several dishes I ordered). Sneaky. I suppose it's harder to notice than a price change. And the food seems "less packed" into their bowls like before - now there is more empty pockets of space.

Pizza Hut, on the other hand, did raise their prices by $1-2 on main pizzas. Toppings feel the same.

Good thing Costco gas is cheap and their money-losing $5 fresh rotisserie chickens are still available.

Among the business maxims Alfred E. Perlman (President of the Penn Central Transportation Company and its predecessor, the New York Central Railroad) is best remembered for is a comment which appeared in the New York Times on July 3, 1958. "After you've done a thing the same way for two years, look it over carefully. After five years, look at it with suspicion. And after ten years, throw it away and start all over."
https://en.wikipedia.org/wiki/Alfred_E._Perlman

Perlman's predecessor was Robert R. Young, who in a deep depression committed suicide on Janary 25, 1958. As I recall, he shot himself in the head with a shotgun.

I've noticed places that offer , e.g., 50% off for lunch , say, until 3 p.m, but then give you around half the original portion or less. And charge you extra for any add-one.

There is no connection between the quote by Perlman and the unfortunate end of Robert Young. Young brought Perlman to the NY Central to improve it, which Perlman did eventually, after Young's suicide.

There were strong economic forces beyond the control of Young and Perlman, and even though both were accomplished, they could not overcome their respective situations. If only Young had held on longer, but then he would have watched the catastrophe of the merger/takeover of the NY Central by the Pennsylvania Railroad into the PennCentral Corporation, and the subsequent bankruptcy.

Penn Central operated a system with 40,000 miles (64,000 km) of track in fourteen states and two Canadian provinces. It had total assets of $6.3 billion and annual revenues of nearly $2 billion. Within two years of merger, competition from trucking on the federally funded Interstate Highway System and the St. Lawrence Seaway, deindustralization in the Northeast and Rust Belt, an economic downturn, strict regulation, heavy taxation, redundant trackage, outdated work rules, the inability to end money-losing passenger services, the forced 1969 integration of the financially disabled New York, New Haven and Hartford Railroad by the Interstate Commerce Commission, coupled with Penn Central's own bungled integration of the merged companies and mismanagement, resulted in the largest corporate bankruptcy in American history to that time.

How do you distinguish a physicist from a mathematician?

Easy. You simply say 'Noether'. If he thinks of groups he is a physicist, and if he thinks of rings he is a mathematician.

I have to confess that, until maybe a year or two ago I had assumed (never having heard anyone say the name, and not knowing any German) that the pronunciation was something like "noy-ther". I now believe it's more like "ner-ter".

The "ö" as in Schrödinger, Noether, or Gödel is difficult for native English speakers. Wiki solves it this way: Oedipus UK: /ˈiːdɪpəs/, US: /ˈɛdə-/ , but I doubt that it comes close. It is a bit like in "urgent", "surf", or "turn". The difficulty is, that the rolling tongue of the American pronunciation should be removed, i.e. without "r" after the "u", which is apparently even more difficult than it is for us to pronounce the "th" correctly.

Sabine can hardly be called a valid reference.

Btw. French and Hungarian have an "ö", too. How do you manage to pronounce Richelieu or Erdös.

US left Afghan airfield at night, didn’t tell new commander

“In one night, they lost all the goodwill of 20 years by leaving the way they did, in the night, without telling the Afghan soldiers who were outside patrolling the area,” said Afghan soldier Naematullah, who asked that only his one name be used.

Within 20 minutes of the U.S.’s silent departure on Friday, the electricity was shut down and the base was plunged into darkness, said Raouf, the soldier of 10 years who has also served in Taliban strongholds of Helmand and Kandahar provinces.

The sudden darkness was like a signal to the looters, he said. They entered from the north, smashing through the first barrier, ransacking buildings, loading anything that was not nailed down into trucks.
Predicted by the Onion 10 years ago.

https://www.theonion.com/u-s-quietly-slips-out-of-afghanistan-in-dead-of-night-1819572778

KABUL, AFGHANISTAN—In what officials said was the "only way" to move on from what has become a "sad and unpleasant" situation, all 100,000 U.S. military and intelligence personnel crept out of their barracks in the dead of night Sunday and quietly slipped out of Afghanistan.

U.S. commanders explained their sudden pullout in a short, handwritten note left behind at Bagram Airfield, their largest base of operations in the country.

"By the time you read this, we will be gone," the note to the nation of Afghanistan read in part. "We regret any pain this may cause you, but this was something we needed to do. We couldn't go on like this forever."
